A cheats app is already on the phone. I also wouldn't recommend using the "All memories" cheat (if you're just starting out for the first time) in case you get stuck at some point in your game. Knowing what images are missing will allow us to be able to see what you still need to do instead of having to look over your save.
The answer was already written earlier.
The only time you wouldn't be able to access the cheats app (or any of the others except for the save/load/quit buttons) would be during the introduction on day 1.
It could be a number of things:
Thank i just installed the codec pack now, lets see if it works
I don't know why people dislike the idea of K-Lite so much. Perhaps once upon a time it was riddled with malware but sure seems to be okay now. It even fixed my DirectX issues when I was having problems with animations in a different game a couple of years ago.
I don't have a K-lite, but have an MPC with its codecs, and I also didn't have any problems with the game.
K-Lite Codecs use LAV videos codecs like all other video players available from the internet
